SPECIFICATION forming part of lIl'letters Eatent No. 704,901, dated July 1 5, 1902.

Application led September 1S, 1901. Serial No. 76,286. (No model.) e

To a/ZZ whom. t may con/cern:

Be it known that I, FERNANDO G. MOORE, a citizen of the United States, residing at San Bernardino, in the county of San Bernardino Iand State of California, have invented new and useful Improvements in Bicycles, of which the following is a specication.

This invention relates to bicycles, and particularly to the front or steering forks thereof, the `object in view being to provide a novel construction of front fork, whereby while retaining all the strength necessary at the same time the fork is adapted to cushion and absorb the jars and concussions` ordinarily applied through the medium of the fork to the frame of the machine, thereby increasing the comfort of the rider and also materiallyT increasing the life of the machine.

With the above and other objects in view,

the nature ofwhich will hereinafter more Similar numerals of reference denote like parts in all the figures of the drawings.

Referring to the drawings, l designates a,

fork-crowmwhich may be of any usual or preferred shape, the same having extending up.

ward therefrom the usual fork-stem 2 of tubillar-construction.

In carrying out the present invention the fork-crown 1 is provided at suitable points with a pair of pendent stubs3, around which are disposed springs 4, which are preferably coiled Aand illustrated as such," although it will be apparent that the shape of the springs may be altered, and, in fact, rubber sleeves or cushions may be employed'in place of the coil-springs.

Arranged beneath the fork-crown 1 is an auxiliary crown or crown-plate 5, which has associated therewith the tubular fork-blades 6, the same opening up through the plate 5 to receive the stubs 3, which are slidingly l mounted therein and adapted to work up and down under the control of the springs 4.. EX- tending upward from `the crown-plate 5 is a tubular Vstub 7, which is slidingly fitted in the lower end of the fork-stem 2. It will now be seen that by reason of the springs 4 being interposed between the crown and crownplate and by further reason of the stubs 3 fitting into the tubular fork-blades 6 and the stub 7 into the stem 2 a limited and yielding sliding movement is established between the fork-blades 6 and the fork-stem 2, with the result that all concussione or jars imparted to the wheel and fork-blades will be absorbed before reaching the fork crown and stem,'and will consequently be prevented from being communicated tothe machineframe tothe discomfort of the rider. Y

In order to conceal the parts by which the above desirable result is accomplished, and to limit the ,upward movement'of, the studs 3 within the fork-blades 6," to obviate all liability of their accidental displacement, and also to prevent the deterioration of springs by the elements, I provide an outer-jacket or casing 8, conforming in shape to the shape of the crown and provided with a body portion 8 and a bottom 8 adapted to engage the under side of the auxiliary crown or crown-plate 5 to limit the upward movement of the studs 3 within -the fork-blades 6 and projecting from the bottom areV pendent culfs 9 which slidingly embrace the upper portions of the fork-blades. This jacket or casing is secured to the fork-crown by means of screws or other suitable fasteners l0, inserted through the jacket or casingV into the crown.

It will be understood that the invention is susceptible of various changes in the form, proportion, and the minor details of construction which may-accordingly be resorted to without departing from the principle or sacricing any of the advantages of this invention. A
